SUMMARY

This discussion focuses on strong-smelling chemicals commonly used in laboratories that require handling under a chemical hood for safety. Key chemicals mentioned include Glacial Acetic Acid, Acetonitrile, Ammonia, and Hydrogen Sulfide. The conversation emphasizes the importance of using fume hoods to prevent inhalation of toxic vapors, particularly highlighting the dangers of Hydrogen Sulfide, which can paralyze olfactory nerves at high concentrations. Participants share personal experiences and caution against relying solely on smell to gauge chemical safety.

PREREQUISITES
  • Understanding of laboratory safety protocols
  • Familiarity with chemical handling procedures
  • Knowledge of chemical properties and hazards
  • Experience with using fume hoods in laboratory settings
NEXT STEPS
  • Research the properties and safety measures for handling Glacial Acetic Acid
  • Learn about the effects of Hydrogen Sulfide exposure and its detection methods
  • Investigate the use and risks associated with Acetonitrile in laboratory settings
  • Explore best practices for using chemical hoods effectively in various laboratory environments
USEFUL FOR

Laboratory technicians, chemists, safety officers, and anyone involved in chemical research or handling who seeks to enhance their understanding of chemical safety and odor management in laboratory environments.

Hi there

Do you all have any chemicals that you can think of in a laboratory that give off a very strong smell and should be used under the chemhood

I just used Glacial Acetic Acid today and I had no idea how strong the smell was . from now on I am using it under the chemhood

I have created a list so far, if anyone has anything else I can add that would be great:
* Acetic Acid (Glacial Acetic Acid)
* Acetonitrile
* Ammonia
* Beta-mercaptoethanol
* Cadaverine
* Chloroform
* Formaldehyde
* Hydrogen sulfide
* Methanol
* N-Butanol
* Oleum
*Paraformaldehyde
* Sulfuric acid
*Trimethylamine
*Virkon

Thanks!

Carbon disulfide. putrecine, skatole (3-methyl indole).
 
It's probably a good idea in the chem lab, as a general safety rule, not to inhale any chemical vapors, even the ones with inoffensive aromas.

That way, you don't need to run around compiling lists, which are going to be problematic to check in a given situation.

As a chemist, I could never resist getting a good whiff of something I'd never smelled before. Chemists years ago used to taste them as well. I used to wash my hands with carbon tetrachloride. And oh, Tester's glue :wideeyed:

The problem with making lists of smelly chemical vapors is that it ignores any which might be odorless but nevertheless still dangerous or toxic.

In particular, hydrogen sulfide has the odor of rotten eggs at low concentrations, but this chemical is notorious for paralyzing the olfactory nerves when inhaled at high concentrations. You literally cannot smell it any longer and think you are no longer in danger, when precisely the opposite is true.

The chem hoods are put in labs for a reason, and not just to satisfy the safety boffins. Use them.
 
Here is a list of them too. I believe all of us have enjoyed the smell of hydrogen sulfide at least once in our lives.
One of the most common smells we always find interesting but is less known or cared about by many is that of the rain, which is caused by an organic compound called geosmin produced a type of soil-dwelling bacteria named actinomycetes.

When I was a research assistant with the Organic Geochemistry Group at FAU, my boss dang near killed himself with nitrogen. He was evaporating down a sample under the hood with a nitrogen blanket over the sample. The flow rate was stepped up, surpassing the hood's capability to evacuate. After a while, his knees buckled and he passed out.
 
Thanks for the suggestion.
